Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 26

What is the result of running the crypto isakmp key ciscXXXXXXXX address 172.16.0.0 command?

Answer options

• A. authenticates the IKEv2 peers in the 172.16.0.0/16 range by using the key ciscXXXXXXXX
• B. authenticates the IP address of the 172.16.0.0/32 peer by using the key ciscXXXXXXXX
• C. authenticates the IKEv1 peers in the 172.16.0.0/16 range by using the key ciscXXXXXXXX
• D. secures all the certificates in the IKE exchange by using the key ciscXXXXXXXX

Correct answer: C

Explanation

The command establishes a pre-shared key for IKEv1 peers specifically within the specified address range of 172.16.0.0/16. Option A is incorrect because it refers to IKEv2 instead of IKEv1. Option B mentions a specific /32 peer, which is not applicable in this context, and option D incorrectly states that the command secures certificates instead of authenticating peers.
